Course description
Java is everywhere and is as popular as ever. This hands-on course, delivered using Java 17, endeavours to provide the fundamental skills you need to become a Java Developer. We'll have you build a series of realistic apps focusing on object-oriented principles from the start.
Note that this is not a beginners course. You are expected to be familiar with programming concepts and have a little coding experience. If not you should consider our Introduction to Programming - Java course instead.
Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
Who will the Course Benefit?The Java Programming 1 / Java Developer course is aimed at anyone with a little coding experience seeking to become a Java Developer, and existing developers seeking to migrate to Java.
Course ObjectivesThis course aims to provide the delegate with the skills needed to build object-oriented apps using Java that exploit all of the fundamental elements of the language.
Upcoming start dates
Suitability - Who should attend?
Delegates attending this course should be able to define general programming concepts including compilation and execution, variables, arrays, sequence, selection and iteration, navigate the filesystem (on the command line ideally), edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming - Java course.
Experience to the level as demonstrated in this course is recommended:
